Does anyone know of any good cardio DVD's? All the ones I have are only 30 minutes and don't challenge me that much...my heart rate doesn't get up there. I can't afford a gym membership, and I live in Minnesota and hate the cold so working out outside isn't an option.

The Biggest Loser dvd w/ Bob Harper is the best cardio workout I've had in a long time. There are four different workouts (plus warm up and cool down). Each workout is about 20 minutes long, but you can combine them however you like. The workouts are low intensity cardio, high intensity cardio, strength and sculpt and boot camp. All of them get my heart rate up there. I can't currently do all the high intensity without stopping to catch my breath several times.

There's supposed to be a new one coming out (or already out) with last year's folks (the one I'm talking about is the Suzy and Matt season). I'll be getting that one, too, to add to my library.

I'd count Ripped 1000 as cardio. You do use some weights but it's mostly as a vehicle to get your heart rate up by making the exercise more challenging. It's really about the cardio. If you've used any of her other DVDs, you'll know that every time you go to a new segment, it tells you what you're about to do. For example, chest, lunges, squats, etc. Here almost every segment is CARDIO!! and I promise you it will kick you in the behind and leave you feeling like you really worked out.
